[0002] In the early stages of automobile manufacturing and in some small workshops, the assembly of components such as cylinder block plugs and bearings relied primarily on manual labor. This traditional assembly method was extremely inefficient, and due to variations in worker skill and physical limitations, it was difficult to ensure precise assembly quality and high consistency for each component. This situation negatively impacted the overall performance and reliability of automobile engines, hindering the further development of the automobile manufacturing industry. Existing intelligent manufacturing cylinder block press-fitting machines have significant functional limitations, often only capable of assembling one side of the cylinder block, unable to complete complex multi-sided assembly processes in one go. When faced with different models and specifications of cylinder blocks, existing press-fitting machines lack sufficient versatility and flexibility, making it difficult to quickly and accurately adapt to diverse production needs. This not only reduces production efficiency but also increases equipment procurement and maintenance costs for enterprises. Utility Model Content

Then, the plug or bearing to be pressed is placed into the clamping slot 55 of the pressing device 5. The elastic retaining spring 56 prevents the parts from falling off. Then, the first motor 2 is started. The output shaft of motor 2 drives the rotating seat 3 to rotate, thereby rotating the quick clamping device 4 fixed on the top of the rotating seat 3 and the clamped cylinder body to meet the assembly requirements of different surfaces around the cylinder body; while starting motor 3 13, motor 3 13 drives screw 2 12 to rotate, causing slide 2 11 threadedly connected to screw 2 12 to move back and forth in the guide groove 2 15 of mounting seat 14, and the connecting seat 6 on the top of slide 2 11 moves accordingly, thereby driving the pressing device 5 to move back and forth to achieve the requirement of precise assembly of the cylinder body at different positions; starting motor 2 10, motor 2 10 drives screw Rotating screw 19 causes slide 18, which is threadedly connected to screw 19, to move up and down within guide groove 17 of connecting seat 6. Pressing device 5, fixed to the front of slide 18, moves up and down accordingly to meet the needs of precise assembly of cylinder bodies at different heights. Finally, hydraulic cylinder 4 58 in pressing device 5 is activated. Hydraulic cylinder 4 58 extends, causing telescopic arm 59 to move to the left within guide hole 1 52, which drives the plug or bearing in clamping groove 55 to quickly approach the position to be assembled.
